COMB-SHEARS.

To all whom it may concern.'

Be it known that I, RICHARD KUHLE, a subject of the King of Prussia, andresident of Berlin, Germany, have invented certain new and usefulImprovements in Comb- Shears, of which the following is a speciiication.

llVith the well known comb shears provided with a lower comb and anupper knife regular cuts cannot be obtained, because the shears only cuttoward one side and must be withdrawn from the hair to bring them backinto their starting position. This is due to the fact that the knife isrigidly connected with the handle and must be so arranged as to form anacute angle with the comb in the direction of the cut in order to beable to cooperate with the comb, and the said oblique arrangementprevents the backward cut as the cutting' edge is directed away from thecomb. In order to overcome these objections, the knife is arrangedaccording to the present invention on the actuating member so that itmay be rotated on a shaft extending parallel to the teeth of the comb.Thus the knife is adapted to exactly follow the comb and to cut forwardas well as backward without it being necessary to withdraw the shearsfrom the hair. By this method of working a regular cut of the hair isobtained and the time required for the work is shortened. If the knifesupported as just described is secured to a pivot in such a manner as tobe adjustable in the longitudinal. direction another advantage is thatthe knife, even when it has been shortened by repeated sharpenii'ig, canalways be brought to the correct position with reference to the combteeth.

Figure l is a top plan view of dog and sheep shears embodying myinvention; Fig. 2 is a top plan view on an enlarged scale of the knifesupporting device; and Fig. 3 is a side elevation view on an enlargedscale of the knife supporting device.

Secured to the spring stirrup c is the handle a carrying the comb CZ aswell as the handle member o carrying the pivot 7i', g for supporting theknife e, provided with two cutting edges. The handle a carries theabutments z' and c for the handle member The pivot 7i, g is formed by athreaded bolt g shown by the drawing, and the knife e is Specificationof Letters Patent.

screwed thereupon. As readily seen during the forward and backwardmovement, the knife e follows the surface of the lower comb cl andslightly rotates forward or backward on the threaded part of the bolt L,g. It results, therefore, that the cutting edges of the knife alwaysapply themselves on the various teeth of the comb, so that a correctforward or backward cut is obtained.

If the knife has been shortened by repeated sharpening, it may bescrewed outwardly on the threaded bolt g to give it such a position thatin spite of it having been shortened, it again occupies the correctposition with reference to the teeth of the comb.

It is needless to say that in place of the threaded bolt g, other meansmay be used, allowing the knife to be rotated. The above describedsupporting means for the knife is not only suitable for sheep shears, orthe like, operated by hand or by power, but also for simple hair cuttingapparatus and beard cutting machines.

Having now fully described my said invention, what I claim and desire tosecure by Letters Patent is l. In a comb shear, the combination with acomb having a handle, the handle carrying two abutments, a handle memberoperating between the abutments, a U-shaped spring connecting the endsof the handle and handle member, and a two-edged cutting knife screwedon the end of the handle member sliding laterally over said comb.

2. In a comb shear, the combination with a comb having a handle, thehandle carrying two abutments, a handle member operating between theabutments, a U-shaped spring connecting the ends of the handle and thehandle member, a threaded bar projecting from the end of the handlemember, and a two-edged cutting` knife having a threaded aperturemounted on the bar whereby the knife is rotatably and longitudinallyadjustable with relation to the teeth of said comb.

In testimony whereof I have hereunto set my hand in presence of twowitnesses.

RICHARD KUHLE.
